The Michelin Airstop Standard 12-inch inner tube is designed for dependable performance in compatible tires requiring a TR-4 center metal valve. Manufactured by Michelin and identified by manufacturer and vendor part number 99377, this tube provides a reliable replacement solution for powersports, utility, and other applications using the correct 12-inch tire and rim configuration.
Its valve placement is opposite the splice, helping create a more balanced tube during installation and operation. The tube uses an overlap splice, which is stronger than the butt splice commonly used in many other inner tubes. This construction supports improved durability and dependable air retention when properly installed.
Michelin Airstop tubes are selected by customers seeking high-quality replacement components from a trusted tire manufacturer. Verify tire compatibility, rim requirements, valve location, and the required TR-4 valve style before installation. The tube should be installed by a qualified technician using appropriate mounting procedures to help prevent pinching, twisting, or damage.
